CUT-MARKER FOR WARP SIZING AND DRYING MACHINES.

SPECIFICATION forming part of Letters'latent No. 432,535, dated July 22, 1890.

Application filed October 10, 1889- To all whom it may concern:

Be it known that 1, WILLIAM G. LovERINe, of Taunton, county of Bristol, State of Massachusetts, have invented an Improvement in Out-Markers for \Varp Sizing and DryingMachines, of which the following description, in connection with the accompanying drawings, is a specification, like letters-on the drawings represent-ing like parts.

In the manufacture of cloth upon looms the weavers are paid by the out, and the manufacturer estimates the product of the loom by the out. To designate these cuts the warp as it is being sized and dried in the sizing and drying machine, or as it is being otherwise prepared for the loom, has some of its threads, especially those which are to appear in the selvage of the woven cloth, marked at intervals to designate the out. At the present time manufacturers are subjected to very considerable loss, for frequently'a weaver will tear off one end of the out after it has been woven and is ready to be removed from the loom. The manufacturer has no means by which to detect this loss unless the out be actually measured when handed in; but this, it willbe seen, is impracticable, because of expense. As now practiced each weaver receives warp sufficient for a number of cuts, and is supposed to return its equivalent in cloth; but a weaver may tear a number of yards of cloth from any out and defy detection, unless at very considerable cost. In my efforts to guard against this loss of cloth I have devised a method of marking the warps prior to weaving the same, whereby such loss may be obviated, and have described the same in another application, Serial No. 326,627. In accordance with my said method the warp during the sizing and drying operation, or before it is put-into the loom to be woven into cloth, is provided with a cut-mark of such width, length, shape, or character that when the warp so marked is woven into cloth the cutmark, together with the filling, produces a cut-figure of such width, length, or shape that when the cloth is severed through the cut-figure to remove a cut from the .loom a part of the cut-figure will be left at the last or finished end of one and at the first or commencement end of the next out. In this way it is impossible for the weaver to retain any (No model.)

cloth without discovery, for the ends of each cut delivered must show parts of the cut-figures, which may be matched, if desired. It has been found that the cut-figures in the woven cloth vary very considerably, even when the cut-marks in the warp are substantially the same, and in practice this variation is sufficient to enable the manufacturer, should he so desire, to positively match the ends of any two consecutive cuts. The form of the cut-mark on the warp, and thus of the cutfigure, may be variously modified, thus enabling each manufacturer to readily tell his own cloth or to tell the cloth woven in any particular mill.

My present invention has for its object the production of a machine by which awarp may be cutanarked in such manner that when subsequently woven into cloth the cloth will present a well-defined cut-figure, parts of which, when the cloth is cut through the cutfigure, will appear at the ends of the cut; The warp is marked by an impression-pad, herein shown as a bar carried by a transverse shaft having co-operating with it a printing-roll, to which is supplied suitable ink or color mixture, the warp being cut-marked at intervals as the warp passes between the pad and roll.

Suitable means are provided for automatically effecting the movement of the marking devices at predetermined or regular intervals, according to the number of yards in the out.

Figure 1 shows in side elevation a portion of a slasher of usual construction provided with marking devices embodying my invention; Fig. 2, a partial rear side view of the machine, chieiiy to show the marking devices; Fig. 3, a sectional detail, chiefly to show the marking devices or apparatus shown in Fig. 2; and Fig. 4 is a plan view of a portion of a slasher and the marking devices shown in Fig. l.

My invention is applicable to any usual slasher or warp dressing or sizing machine; but herein I have selected a machine substantially such as represented in United States Patent No. 346,639, with which to embody my invention.

Referring to the drawings, A represents the frame-work, which may be of any suitable shape to support the working parts.

The section-beam stand 1, which in practice supports any desired number of sectionbeams 2 to contain threads to constitute the warp 7 to be acted upon, the guide-rolls 3, fl, and 10, the immersing-roll 5, the two pairs of squeczing-rolls 6, between which the warp is passed, the size-vat at, in which the said rolls operate, the drying-cylinder S, the shaft 21, and the devices (not here shown) for rotating the said cylinder and shaft, are and may be all as shown in the patent referred to. In practice the drying-cylinder 8 maybe rotated either as described in the said patent or in any other usual or suitable manner, and if the drying-cylinder should be rotated by the warp then the squeeze-rolls might be rotated only by the warp passing between them. lt will however be assumed that the shafts 67 of the lowermost rolls of the pairs of rolls 6 in the size-vat are provided with like pinions to outside the size-vat, as represented in Fig. 1, and that the said pinions are engaged by a pinion 21-, immediately back of a bevel'gear 23 011 a shaft- 25, the end of which is shown by dotted lines in Fig. 1, and that the bevel-gear 23 is engaged by a bevel-gear 22 on the shaft 21, and that the lowermost rolls 6 are thus rotated positively in the direction of the travel of the warp.

The parts so far referred to are old and connnon, and instead of the devices shown or referred to for rotating the rolls 0, I may employ any other well-known or suitable mechanism.

The mechanism illustrated in the drawings, which has been so far described, is not claimed by me.

I have applied to the slasher or sizing-machine, between the point at which the warp is sized and the point at which it is dried, cut-marking mechanism or devices, one form of which I will now describe.

The shaft 25 referred to is represented as extended through the size-vat, and at its end farthest from shaft 21 it is provided with a pinion 27, (see Fig. 2, which engages an intermediate pinion 28, loose on asuitable stud 29, the said intermediate pinion 2S engaging a pinion 30 on the journal of and rotating the ink-roll 81, the lower surface of which is shown as turning in an ink well orsupply 32. The journal of the ink-roll 31, justinside the frame of the machine, has attached to it (see Fig. asecond toothed pinion 33, of the same size as the pinion 30 and directly behind it. The pinion engages a pinion 3t fast on the journal of and rotating the printing-roll a. The surface of this printingroll is in contact with the inked surface of the inking-roll, so that the printing-roll has applied to ita thin film of ink.

I do not desire to limit n'lyinventionto supplying the printing-roll with ink or coloring matter in the exact manner described, as it may be inked by other usual equivalent devices.

Rising from the size-vat, or from some other rigid part of the machine, are standards I), which form bearings for the journals 1; of a marker, herein shown as composed of a shaft U and an impression pad or bar I). The impression pad or bar U, as herein shown, has near each end threaded rods 1), which are extended loosely through suitable transverse holes in the shaft 1) the said rods being thereafter provided with nuts, as U", to preventtheir withdrawal from the bar. The pad or bar is normally pushed out radially from the shaft 7) by springs, herein shown as spiral sprin c, which surround the rodsh between the pad or bar Z1 and shaft IF, the said springs serving to hold the pad orbarin such manner that it may yield as the pad or bar in its rotation with the shaft h meets the warp 7, the said pad or bar acting at such time to press the warp against the inked surface of the printing-roll 0, thus printing upon the said warp a cut-mark, the size and shape of which may be varied as represented in my said application, that depending upon the shape of the face of the pad or bar of the marker. The shaft W, as shown, has fixed to it at one end a mutilated pinion (7, which maybe thrown into mesh with the pinion 3- as will be described, whenever the marker is operated to form a cut-mark. The shaft Z1 has also fixed upon it a notched plate 6, which is normally engaged by a latch c, pivoted at c as best shown in Fig. 1, the said latch c, when in engagement with the notched plate 0, keeping the pad orbar in elevated position and at rest. The latch e will in practice he acted upon at one en d by a finger or projection, as f, it forming a slowly-moving part of any usual socalled clock mechanism, as f, containing usual gearing, whereby the finger may be actuated to make one rotation for each cut, the said clock mechanism, as herein represented, deriving its motion from a worm f on a shaft/ having a beve1-gearf, which is in mesh with and is rotated by a bevel-gear on the shaft f of the dryingcylinder S; or the clock mechanism may be operated in any usual manner from some moving part of the machine.

In general the construction of the so-called cloclnnechanism or counting mechanism may be of any suitable or usual construction, such as employed in mules and other machines to record movements.

Whenever the finger or projection f of the clock mechanism acts to lift. the forward end of the latch c from the notched disk 6, the pad or bar I) by gravity drops and comes in contact with the warp 7 and in falling brings the teeth of the mutilated pinion (Z into ongagement with the teeth of the rotating pinion Sl, which latter pinion thereafter acts to rotate the shaft 1) until, as herein shown, the pad or ,bar 1) passes the top center of the shaft U when it begins to drop by gravity, and thereafter its descent is arrested by the latch e engaging the notched plate c. XVhile the pinion 3t and the mutilated pinion I] are warp from at or near one selvage to at or near the opposite selvage, the cut-mark being-of such size'and shape that when the warp is Woven in a loom the cut-mark so made upon the warp will produce whatl denominate a cut-figure, so that when the cloth is divided in order to remove a cut from the loom a portion of the cut-figure will be on the removed cut and its other portion will be upon the cloth or cut remaining in the loom I claim 1. The printing-roll, combined with the impression pad or bar and shaft carrying it, and with means to revolve the said shaft at predetermined intervals to print a cut-mark on the warp-threads from at or near one edge to at or near the other edge, substantially as described.

2. A printing-roll, an impression pad or bar, and means to supply color to the printing-roll, combined with means for holding said impression-pad in inoperative posit-ion and for:

releasing it, and means to rotate the said impression pad or bar when so released and cause it to co-operate with the printing-roll to produce cut-marks upon the interposed warp, substantiall y as described.

3. The printing-roll and the inking-roll combined with an impression pad or bar and a shaft to which it is attached loosely, and with means, substantially as described, for revolving said shaft at predetermined intervals, as set forth.

4. The printing-roll and the inking-roll combined with an impression pad or bar, a shaft to which it is attached, a mutilated pinion fixed to said shaft, means, substantially as described, for holding and releasing said shaft, and with a driving-pinion to engage the said mutilated pinion and revolve the shaft carrying the impression pad or bar at predetermined intervals, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
